Vitrified Bond Wheels
Vitrified bond is a vitreous binding material and generally contains pores inside while other materials contain no pores. Therefore vitrified bond wheels have excellent grinding ability and are superior in forming.
(1) Characteristics of Vitrified Bond Wheels
1.Wheelgrinding ability and wheel life depend on the combination of binding material, super abrasive mesh size, concentration, and porosity. The harder the bond, the longer wheel life is achieved.
On the contrary, the softer the bond, better grinding ability is achieved because porosity becomes higher. Also higher concentration of abrasive, equates to longer wheel life.
2.Automated processing is available because simultaneous operation of truing and dressing using rotary dresser on the grinding machine is possible.
3.Cutting edges can be manipulated in such a manner that the surface finish of the part can be controlled.
4.Diamond wheels have difficulty in truing and dressing with rotary dressers. Therefore surface finish depends on the mesh size of super abrasive in the diamond wheel.
(2) Application of Diamond wheels
1.They are efficiency used for grinding difficult-to-machine materials such as PCD, PCBN, ceramics, etc.
2.They are generally superior in grinding ability to metal bond wheels. Because the vitrified bond has no elasticity, it is better suited for tight tolerance applications than resin bond wheels.
(3) Application of CBN Wheels
1.They are used for grinding ferrous materials such as automotive parts(camshafts, crankshafts, gears, CVJ, etc.), bearing parts, household appliance parts(compressors, motor shafts, etc,), and cutting tools.
2.CBN abrasive has superior heat stability thus providing excellent performance in super high-speed grinding to process camshafts, crankshafts, etc.
